I have a Precision Pro Spreader with settings 1-10. Lesco has my (lesco) spreader and I cant get ahold of them to pick up my spreader or fert! I would like an idea of what to set this thing at to put Scotts Turf Builder + halt. Ive been dicking around with this for a few days and need to get this stuff down asap! Don't knock me for buying Scott's fert, I believe my lesco dealer is out of business and I want my spreader back! What do I set this Precision Pro at? This is for my own lawn as I sub all fert and other apps. out! Thanks! Jus trying to get my own lawn looking good!
